LAN IP Addressing
If the default gateway is not on the same subnet as the PC and the router LAN IP address is not on the
same subnet as the PC, the default gateway of the PC is not modified, and the router is configured with
the IP address entered by the end-user.
The flag is automatically enabled when Setup connects the PC to the router by using a Telnet session.
If the PC is connected to the router by using the console cable, this flag is implemented only if the
SetAutomaticChangeIPStackWhenNeededByFastSTep flag is set to 0 and the
SetChangeIPStackOnConsole flag is set to 1.
The flag syntax is as follows:
[PC Settings]
UsePCGatewayAsRouterLANIP=
If this flag is set to 0 or blank, the PC gateway address is not set to the router LAN IP address.
If this flag is set to 1, the PC gateway address is set to the router LAN IP address.
Set the Router LAN IP Address as the PC Default Gateway
This flag sets the router LAN IP address to the PC default gateway address, so the PC can communicate
with the router. If the router LAN IP address is not on the same subnet as the PC, this flag is ignored,
and nothing is changed.
If the flag UsePCGatewayAsRouterLANIP is set to 1 and the UseRouterLANIPAsPCGateway flag is
set to 1, the UsePCGatewayAsRouterLANIP flag is given the preference, and the
UseRouterLANIPAsPCGateway flag is ignored.
For a Telnet connection, if the DHCP server is not enabled on the router and this flag is set to1, Setup
checks the PC default gateway IP Address and the router LAN IP address. If they are different, Setup
sets the PC gateway with the router LAN IP address.
For a console cable connection, Setup checks the SetChangeIPStackOnConsole flag. If it is set to 1 and
the UseRouterLANIPAsPCGateway flag is set to 1, Setup sets the router LAN IP address as the PC
default gateway. If DHCP server is enabled on the router, this flag is not used.
The flag syntax is as follows:
[PC Settings]
UseRouterLANIPAsPCGateway=
If this flag is set to 0 or blank, the router LAN IP address is not set to the PC gateway address.
If this flag is set to 1, the router LAN IP address is set to the PC gateway address.
DHCP Relay Configuration
Setup can configure the DHCP relay on the router. This can only be configured by using the CFG file;
the user is not prompted for this information, and it cannot be configured through a TPL file.
The SetDHCPRelay flag turns DHCP relay on, and the RemoteDHCPServerAddress flag sets the IP
address of the DHCP server. The command-line syntax is as follows:
RemoteDHCPServerAddress
